1. Motorcycles are a popular form of transportation. They are often seen as faster, cheaper and more convenient than cars. Motorcycles also have many advantages over other forms of transportation. For example, because they are cheaper to buy and maintain, they can be a more affordable option for commuters who live in congested urban areas where parking is scarce and expensive. As well, motorcycles offer better fuel efficiency than cars because the rider does not have to use the engine to power air conditioning or heat like a car does. Motorcycles also provide an easy way for riders to get around in tight spaces like city streets and parking lots that are too small for cars.

2. The disadvantages of motorcycles include the fact that they are difficult to operate. Motorcycles are not a very good option to commute because of the safety risk. Motorcycles have a higher fatality rate than cars, so it is not worth the risk of getting in an accident.  There is also less storage space on motorcycles for items such as groceries or luggage.

Nowadays we have wide variety of opportunities to choose where we go to shopping- a supermarket, small shop or market. So now let's find out the pros and cons of supermarkets.
From my point of view, the pros of supermarkets include their benefits in terms of food choices, price, convenience, and access to information about products.  For example supermarkets are more enconomical than small shops. They offer goods at cheaper prices and higher quality. What’s more, supermarkets have wide variety of products. It is easier for customers with special needs or tastes to find what they want. Besides, supermarkets open longer hours than small shops and markets. Therefore, convenient for customers who work during the day.
On the other hand, there are some disadvantages to the supermarket too. In my opinion, supermarkets offer impersonal service. There is no relationship between staff and customers. Moreover, supermarkets are often located out of town. And so only people who have a car can shop there.
After reading this article, you should be able to decide whether or not you want to shop at a supermarket based on your preferences, needs and lifestyles.

Environment plays an important role in human life.
The natural world provides us with many benefits, because it is natural surroundings, which helps human beings, animals, plants and other living things exist and develop.Nevertheless, too many people have the misconception that the natural world is not important to their lives. In fact, environmental pollution can have many serious consequences. Any kind of disturbance has significant effects on nature’s balance which will directly influence human life. The natural world is changing and humans need to start protecting it if we want to continue to have a natural environment. From my point of view, it is changing and some animals are going extinct which can change the natural ecosystem. We need to protect the earth in any way possible. There are many methods people can take to protect the environment. For instance, should not use a lot of chemicals, turn off all electrical equipment if not in use, minimize the use of plastic bags and plastic materials,....It is necessary and important to protect the natural world, not only for ourselves, but also to provide a better future for our children.
Through changing lifestyles and attitudes, we can all contribute to protecting this crucial part of our Earth.

Air pollution is a most serious problem of the current time all over the world especially in the large cities because of the huge level of industrialization. The air pollution is also dangerous for people in my area. There are two problems about causes and effects. About causes, firstly, many vehicles discharge dust and smoke into the environment. Besides, factories dump waste poison out. Finally, people littering anywhere, such as parks, beaches, schools and even on the way. About effects, firstly, The polluted air we breathe every moment causing lungs disorders and even lung cancer thus affecting the health of other body organs.

2. Children should start using digital devices when they reach primary school age. Do you agree?
I do not agree children should start using digital devices when they reach primary school age,  because I see a lot of their disadvantages.  In the age of technology booming, application of electronic devices in education has become a common sense. But when children reach primary school age, they are too young to access Internet on their own. Some harmful effects can be mentioned as electronic devices can distract children from their studies as they may use them to play games, text and chat in lesson time. Additionally, children have access to inappropriate information, videos and pictures. Besides that, electronic devices make their eyes tired. This is absolutely not good for the development of children. Last but not least, electronic devices make children less communicate. When children turn to less disclose, they only try to stay at home and play games.

Subject: Invitation for a business trip in Vietnam
Dear Mr. Arthur,
I am writing this email to inform you that you are invited to Vietnam for talking a business trip to Vietnam. Your trip will take place in Hanoi from 11th to 15th May. During the trip, you will visit different places in Vietnam to get more understand of our country.
During your visit, there may be some cutural shock that happens, so I would like to give you some notice to make sure that your trip will be successful. Firstly, in Vietnam, it is regarded as being impolite if a person uses only the first name to address people who are older than him. Therefore, when meeting people older than you, you should call them with Sir or Madam. Secondly, touching other people's heads has to be avoided in Vietnam because it is disrespectful in Vietnamese culture. Finally, Vietnamese people belive that it is impolite if someone eats food right after getting it from the plate. Therefore, in the meal, after talking food from the shared plate, you should put it into your bowl before eating. With these advice, I hope that you can anticipate the problems and over them more easily.
Please confirm your attendance on or before 1th May by contacting us at 0944306298 or emailing us at host.conference@gmail.com.

With the rapid growth of technology in recent years, it is argued that computers are the most important of last hundred years. Personally, I completely agree with this point of view because computers changed the way we live and made our life easier.

Firstly, computers changed the world. People can not deny that computers are crucial tools in our daily life as well as in our works. On the grounds that computers can work more efficiently than us and can store a huge amount of data that are easily accessible all over the world. For example, when using computers in the library, students can find information from reliable sources easily. This helps to improve their lack of knowledge.

Secondly, computers made our lifes easier and more comfortable. Before computers were invented, it took a great amount of time to do things. However, with the support of computers nowadays, everything can be done within seconds. For instance, There will be no more days or months waiting for a letter like our parents did in the past. Messages are sent, read, and replied quickly.

To sum up, in my opinion, computers are the most outstanding machine invented in the last hundred years.

Dear Sir,

As per the subject, I wish to make a formal complaint against your restaurant staff last evening over their bad service, which spoiled my evening with my family.

We came to your restaurant last evening to enjoy with each other and spend some good time .You must be ware that we are a regular guest of your hotel and referred my family to your restaurant. But since yesterday I am very much annoyed with the poor services which you staff has served last evening. I came there with my family for a special occasion, it was my birthday so I was excited for the meal that day. Then we have ordered some european food with some starters.

Now, first of all they took half an hour to serve the food although not many people came to the restaurant that day. They serve in a very slow and superficial way. What bothers us more is that when the food is served to the table, it is already cold and it is no longer attractive. We reported this to the staff but they probably didn't care too much about what we said.

I hope that you will look into this matter and train your staff properly in order to have the appropriate behavior and proper listening ability to save them from future problems

Yours sincerely,

My
